NF ISO 16028, E48-056 (06/2023)

This document specifies interface dimensions for interchangeability and specifies performance requirements for flat face type hydraulic quick couplers for use at pressures from 10 MPa (100 bar) to 31.5 MPa (315 bar) , depending on the connection dimension. Fittings conforming to this document are not designed to be connected or disconnected under pressure. Fittings conforming to this document provide automatic sealing of the fluid pressure on both the upstream and downstream sides when the fitting is disconnected.
